AI Technical Summary
[0002]衬砌钢筋台车上有很多必要的线缆(线缆包括电线和管路)来保证衬砌钢筋台车的正常运行，由于衬砌钢筋台车上的线缆走线主要集中在钢制底纵梁附近，传统的线缆收纳整理方法使用集中捆扎的方式进行，而这就导致了线缆垂悬在钢制底纵梁附近，在隧道的复杂工作环境下，垂悬的线缆容易被碰、刮、钩、扯导致破损或断裂，且在衬砌钢筋台车行走时，垂悬的线缆因台车的行走摇摆而增加断裂的风险，所以线缆的收纳工作很有必要
[0012]与现有技术相比，本实用新型的有益效果是：对于衬砌钢筋台车上的线缆走线主要集中在钢制底纵梁附近的衬砌钢筋台车来说，将线缆固定在钢制底纵梁处是优先的选择，由于钢制底纵梁作为台车的承重主体之一，增加钢制底纵梁的结构强度也是很有必要的，通过对加强钢板的改进，使其具有增加钢制底纵梁结构强度、收纳线缆的功能，对于不容易发生故障的线缆来说(如电线)，在安装该特性的线缆时，可以通过将线缆穿过U形槽被限位，线缆被U形槽限位时，线缆有更大的面积贴合在钢制底纵梁的表面，获得更好的托举稳定效果，而对于容易发生故障的线缆来说(如柔性的液压管路，台车主要依靠液压泵提供能力，恶劣的工作环境以及高负载下容易出现液压管路泄漏)，维修时需要解除被限位的条件，那么可以选择将该特性的线缆放入L形槽中，便于取出进行更加方便的维修。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel excavation technology, specifically relating to a tunnel intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure. Background Technology
[0002] The lining steel reinforcement trolley has many necessary cables (including wires and pipes) to ensure its normal operation. Since the cables on the lining steel reinforcement trolley are mainly concentrated near the steel bottom longitudinal beam, the traditional method of cable storage and organization is to use centralized bundling. This results in the cables hanging down near the steel bottom longitudinal beam. In the complex working environment of the tunnel, the hanging cables are easily bumped, scraped, hooked, or pulled, leading to damage or breakage. Moreover, when the lining steel reinforcement trolley moves, the hanging cables are at increased risk of breakage due to the swaying of the trolley. Therefore, cable storage is very necessary. Utility Model Content
[0003] To address the problems mentioned in the background section, this invention provides a tunnel intelligent rebar trolley load-bearing beam structure with integrated storage and reinforcement. Through improvements to the reinforcing steel plates, it achieves increased strength of the steel bottom longitudinal beam structure and the ability to store cables.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a tunnel intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure, including a steel bottom longitudinal beam, a reinforcing steel plate welded to the outer side of the web of the steel bottom longitudinal beam, and L-shaped grooves and U-shaped grooves for cables to pass through on the reinforcing steel plate. After the reinforcing steel plate is welded to the steel bottom longitudinal beam, the U-shaped groove forms a closed structure and the L-shaped groove leaves a lateral notch on the reinforcing steel plate.
[0005] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure in this utility model, the L-shaped groove on the reinforcing steel plate is located above the U-shaped groove.
[0006] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure of this utility model, the reinforcing steel plate includes groups of upright reinforcing steel plates and inverted reinforcing steel plates, wherein the upright reinforcing steel plates and inverted reinforcing steel plates in each group do not contact each other.
[0007] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure in this utility model, in the orthogonal projection view of the upright and inverted reinforced steel plates in the same group, the overlap of the two L-shaped grooves forms a coincident intermediate hole.
[0008] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure of this utility model, in the orthogonal projection view of the upright and inverted reinforced steel plates in the same group, the overlap of the L-shaped groove and the U-shaped groove forms a coincident side hole.
[0009] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure for tunnels with integrated storage and reinforcement structure of this utility model, a support plate is provided at the bottom of the L-shaped groove of the inverted reinforced steel plate.
[0010] As a preferred embodiment of the intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure in this utility model, the free end of the pallet is in contact with or welded to the surface of the steel bottom longitudinal beam.
[0011] As a preferred embodiment of the intelligent steel reinforcement trolley load-bearing beam structure with integrated storage and reinforcement structure in this utility model, the pallet is formed by bending the plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: For lining steel reinforcement trolleys where cable routing is mainly concentrated near the steel bottom longitudinal beam, fixing the cables to the steel bottom longitudinal beam is the preferred option. Since the steel bottom longitudinal beam is one of the main load-bearing components of the trolley, increasing its structural strength is also necessary. By improving the reinforcing steel plate, it can increase the structural strength of the steel bottom longitudinal beam and accommodate cables. For cables that are not prone to failure (such as electrical wires), when installing such cables, they can be limited by passing them through a U-shaped groove. When the cables are limited by the U-shaped groove, they have a larger area to adhere to the surface of the steel bottom longitudinal beam, resulting in better lifting and stability. However, for cables that are prone to failure (such as flexible hydraulic lines, where the trolley mainly relies on the hydraulic pump for power, and hydraulic line leaks are prone to occur under harsh working environments and high loads), it is necessary to release the limiting condition during maintenance. In this case, the cables with this characteristic can be placed in an L-shaped groove for easier removal and maintenance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-7 As shown:
[0025] A tunnel intelligent steel bar trolley load-bearing beam structure with integrated storage and reinforcement structure includes a steel bottom longitudinal beam 1. A reinforcing steel plate is welded to the outer side of the web of the steel bottom longitudinal beam 1. The reinforcing steel plate has an L-shaped groove 5 and a U-shaped groove 6 for cables 4 to pass through. After the reinforcing steel plate is welded to the steel bottom longitudinal beam 1, the U-shaped groove 6 forms a closed structure and the L-shaped groove 5 leaves a lateral opening on the reinforcing steel plate.
[0026] The lining steel reinforcement trolley has many necessary cables 4 (including wires and pipes) to ensure its normal operation. Since the cables 4 on the lining steel reinforcement trolley are mainly concentrated near the steel bottom longitudinal beam 1, the traditional method of cable 4 storage and organization is to use centralized bundling. This results in the cables 4 hanging down near the steel bottom longitudinal beam 1. In the complex working environment of the tunnel, the hanging cables 4 are easily bumped, scraped, hooked, or pulled, leading to damage or breakage. Moreover, when the lining steel reinforcement trolley moves, the hanging cables 4 are at increased risk of breakage due to the swaying of the trolley. Therefore, the cable 4 storage work is very necessary.
[0027] For lining steel reinforcement trolleys where the cable 4 is mainly concentrated near the steel bottom longitudinal beam 1, fixing the cable 4 to the steel bottom longitudinal beam 1 is the preferred option. Since the steel bottom longitudinal beam 1 is one of the main load-bearing components of the trolley, it is also necessary to increase the structural strength of the steel bottom longitudinal beam 1. By improving the reinforcing steel plate, it can increase the structural strength of the steel bottom longitudinal beam 1 and accommodate the cable 4. For cables 4 that are not prone to failure (such as electrical wires), when installing cables 4 with this characteristic, they can be limited by passing the cable 4 through the U-shaped groove 6. When the cable 4 is limited by the U-shaped groove 6, the cable 4 has a larger area to fit against the surface of the steel bottom longitudinal beam 1, resulting in a better lifting and stability effect. However, for cables 4 that are prone to failure (such as flexible hydraulic lines, where the trolley mainly relies on the hydraulic pump for power, and hydraulic line leakage is prone to occur under harsh working environments and high loads), it is necessary to remove the limiting condition during maintenance. In this case, the cable 4 with this characteristic can be placed in the L-shaped groove 5 for easier removal and more convenient maintenance.
[0028] In an optional embodiment, the L-shaped groove 5 on the reinforcing steel plate is located above the U-shaped groove 6.
[0029] In this embodiment, the U-shaped groove 6 is used for cables 4 that are not prone to failure. When the L-shaped groove 5 is located above the U-shaped groove 6, the U-shaped groove 6 fixes the cable 4, and the cable 4 has a larger area to adhere to the surface of the steel bottom longitudinal beam 1, thereby obtaining a better lifting and stabilizing effect.
[0030] In an optional embodiment, the reinforcing steel plate includes groups of upright reinforcing steel plates 2 and inverted reinforcing steel plates 3, wherein the upright reinforcing steel plates 2 and inverted reinforcing steel plates 3 in each group of reinforcing steel plates do not contact each other.
[0031] In this embodiment, the design of combining the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 can further optimize the fixing effect of the cable 4. Since there are many cables 4 on the lining steel trolley and the space at the web of the steel bottom longitudinal beam 1 is limited (so the volume of the reinforcing steel plate cannot be very large), under the condition that the reinforcing steel plate itself has the structural strength of reinforcing the steel bottom longitudinal beam 1, the space of the L-shaped groove 5 and the U-shaped groove 6 on the reinforcing steel plate with limited size cannot be very large. Therefore, when the number of cables 4 in the L-shaped groove 5 is piled up, the upper cables 4 may be piled up to the side opening of the L-shaped groove 5, making it easy for the cables 4 located at this position to fall from the side opening of the L-shaped groove 5. So, the upright and inverted reinforcing steel plates are formed into a group, and the cables 4 are fixed together by the two L-shaped grooves 5 with opposite opening directions, thereby improving the fixing effect of the cables 4. So, when installing the cable 4, first put the cable 4 into the opening of one of the L-shaped grooves 5, and then bend the cable 4 to enter the other L-shaped groove 5, thereby realizing the placement of the cable 4.
[0032] The spacing between each set of reinforcing steel plates can be selected according to the characteristics of the cable 4, including flexibility, weight, and diameter. The preferred spacing is 1.5 meters. The spacing between the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 in the same set also needs to be selected according to the characteristics of the cable 4 to ensure that the cable 4 can enter the two L-shaped grooves 5 from the side of the reinforcing steel plate through bending, and is finally limited by the two L-shaped grooves 5.
[0033] In an optional embodiment, in the orthographic projection view of the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 in the same group, the overlap of the two L-shaped grooves 5 forms a coincident intermediate hole 8.
[0034] In this embodiment, as Figure 6 and Figure 7 As shown, the size comparison of the overlapping areas in the orthographic projection view of L-shaped grooves 5 and U-shaped grooves 6 of different sizes is shown respectively. The overlapping middle hole 8 is the area where the two L-shaped grooves 5 in the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 jointly limit the cable 4.
[0035] In an optional embodiment, in the orthographic projection view of the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 in the same group, the overlap of the L-shaped groove 5 and the U-shaped groove 6 forms the overlapping edge hole 9.
[0036] In this embodiment, as Figure 6 and Figure 7 As shown, the size comparison of the overlapping area in the orthographic projection view of L-shaped groove 5 and U-shaped groove 6 of different sizes is shown respectively. The overlapping edge hole 9 is the area in which L-shaped groove 5 and U-shaped groove 6 jointly limit the cable 4 in the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3.
[0037] In an optional embodiment, a support plate 7 is provided at the bottom of the L-shaped groove 5 of the inverted reinforcing steel plate 3.
[0038] In this embodiment, when the inverted reinforcing steel plate 3 is present, the cable 4 cannot directly contact the surface of the steel bottom longitudinal beam 1 due to the influence of the bottom support 302 structure of the inverted reinforcing steel plate 3. Without the assistance of the support plate 7, the bottom support 302 has a small contact area with the cable 4, resulting in high pressure. In addition, the cut surface of the bottom support 302 during production is uneven, which can easily damage the cable 4. Therefore, the support plate 7 is set at the bottom support 302 to support the cable 4, thereby reducing the damage to the surface of the cable 4 caused by the high pressure and unevenness of the bottom support 302.
[0039] In an optional embodiment, the free end of the tray 7 is in contact with or welded to the surface of the steel bottom longitudinal beam 1.
[0040] In this embodiment, this arrangement makes the tray 7 an inclined plane, thereby minimizing the risk of the free end of the tray 7 causing compression damage to the cable 4.
[0041] In an alternative embodiment, the tray 7 is formed by bending the retaining plate 301.
[0042] In this embodiment, the upright reinforcing steel plate 2 and the inverted reinforcing steel plate 3 can be formed by wire cutting. However, for the processing of the pallet 7, to reduce production difficulty and speed up production, when wire cutting the inverted reinforcing steel plate 3, the inverted reinforcing steel plate 3 is first cut into a structure common to both the inverted reinforcing steel plate 3 and the retaining plate 301 (e.g., Figure 5 As shown), the bottom of the retaining plate 301 remains connected to the inverted reinforcing steel plate 3, while the other three sides of the retaining plate 301 are cut off from the inverted reinforcing steel plate 3. Then, by bending, the retaining plate 301 is bent into the shape of the support plate 7 along the edge connected to the inverted reinforcing steel plate 3.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
